Vedclass · Answer

(D) Hydrogen bonding occurs when a hydrogen atom is covalently bonded to a highly electronegative atom like $N, O,$ or $F$.In $HF$,$H$ is bonded to $F$,which is highly electronegative,allowing for hydrogen bonding.In $NH_3$,$H$ is bonded to $N$,which is also highly electronegative,allowing for hydrogen bonding.In $H_2S$ and $PH_3$,the central atoms ($S$ and $P$) are not sufficiently electronegative to support hydrogen bonding.Therefore,only $HF$ and $NH_3$ exhibit hydrogen bonding.

Compounds showing hydrogen bonding among $HF, NH_3, H_2S$ and $PH_3$ are
